I have the eAR Two (2-channel) amp, and I concur with Daniel and Ramy. If you can forgive some of its ergonomic quirks (like the connector "cave"), then you'll discover that it is an excellent sounding amp. Peter has since re-designed the connector layout, so today's amps are altogether more user-friendly. I'll add that if you value a sound that's transparent, neutral and 3-dimensional, then this amp deserves to be on your short list. However, if you favour a more overtly euphonic or "warm" sound, then you would be best served by looking elsewhere.
With all due respect to the H2O, I'm sure it is a fine amp but there is currently another thread dedicated to it. Let's allow this thread to remain on topic.
